About this product
OVERVIEW
This aftermarket intake boot flange restores airtight sealing between the carburetor and intake tract, eliminating vacuum leaks that compromise idle stability and throttle response. Engineered as a direct fuel-system replacement component for Arctic Cat snowmobiles, the unit uses thick reinforced rubber to maintain structural integrity and precise carburetor alignment in freezing trail conditions.
ENGINEERING & PERFORMANCE
The flange stabilizes air/fuel delivery by closing off critical vacuum pathways, eradicating bogging and inconsistent throttle progression caused by aged seals. Constructed from heavy-duty reinforced rubber, the boot resists cracking and hardening under severe temperature swings and chassis vibration. Its dimensionally stable design ensures seamless mounting to Mikuni VM36 and VM38 carburetors, delivering factory-grade tolerances that keep cold-start performance predictable and reliable.

WHY RIDERS CHOOSE THIS
Vintage Arctic Cat owners rely on this intake flange because it permanently solves recurring air leaks, hanging idles, and sluggish throttle feedback that plague aging Mikuni setups. The reinforced rubber composition maintains a tight seal even during deep-cold rides, directly preventing the vacuum loss responsible for bogging and poor running. Riders prefer this upgrade because it matches factory dimensions perfectly, outlasts brittle original boots, and returns classic sleds to dependable, consistent airflow without requiring complex modifications.
